TRIPLE-MOTION SASI-I AND HINGE FOR CASEMENT WINDOWS.

Application filed May 25, 1927. Serial No. 193,987.

My invention relates to casement windows less faulty because of not being rain; wind more particularly in which the sash is deand dust proof. Outwardly swinging casesigned to swing inward. The object of the ment sash do not admit of outside screens improvement is to provide a casement sash usually preferred to screens inside. The inso hung to swing inward and when closed vention herein set forth and described is de-. St to be rain-proof and dust tight; and a fursigned to overcome these faults and prother object is to provide a casement window vide an inwardly opening casement sash that in which a window screen may be hung on will be tight and easily operated. the outside and not interfere with the oper- Referring to the drawing the usual form ation of the casement sash. of a casement window is indicated, the frame I attain these objects by means of the referred to as 1 and the sash as 2.

Mounted on the disk 7 and exof the detachable and reversible leaves of tending to the rear through the face plate 8 the top and bottom hinges respectively, and is a stud 10 that engages a tubular foot 4.0 Fig. 18 is a front and side view of a flat leaf bolt 11 in the lower end of which is tightly spring to be fixt in the back of the rabbetof fitted a rubber foot piece 12. This tube 11 the frame near the top and opposite the top is split on one side at 13 andis fitted to hinge to thrust the sash out at the top when slide in a solid sockettube 14; to be liXt in the same is lifted for opening. This memthe bottom of the sash 2 as indicated in 45 ber is not shown elsewhere on the drawings Figs. 1, 2 and 8. The rubber foot piece 12 as but will be referred to in the specification. so expands thesplit tube' ll as to cause a Similar characters refer to similar parts friction with the encircling liXt tube 14. in the several views. This holds the rubber foot 12 steady when Heretofore casement windows with sash turned down on the friction plate 15 shown made to swing inwardly have been more or inFigs. 5 and 8. The foot 12 is set by turn-M 109 ing lift bar to the right till the stud pushes the tube '11 down tight.

In order to lift the sash clear of the rabbeted stool 3, special motion hinges have been devised as shown in Figs. 12, 13, 14 and 15; Each hinge is made with one usual form of leaf 16 to be screwed to the side jamb of the window frame. The opposite leaf 17 is made double and narrow and so spaced apart as to admit of inserting a removable and reversible leaf plate 18 for the top hinge and 18 for the bottom hinge to be screwed to the sash. The plate 18 is provided with two inclined slots 19-19 through which rivet screws 20 are set through the double narrow leaf 1?. The leaf plate '18" has vertical slots i9"19 through which screw rivets are set as in the top. hinge. These leaf plates are fixt to the sash so as to be'in alinement with the leaves 16 when the easement sash is closed the same as when the present form of hinge is used.

The sash 2 now being hung and closed within the window frame as shown in Figs. 1 and 2, the sash is opened by lifting up on the sash lift bar 6. The sash leaf plates 18 and 18' will slip up between tie narrow double leaves 17. The inclined slots of the top hinge will thrust the top of the sash toward the interior of the building causing the beveled side or lip of the sash rabbet 5 to clear the top jamb of the window frame as shown in Fig." 3. The slots'1919 in the bottom hinge being vertical, will cause thebottom of the sash to lift straight up and thus clear the rabbet of the window stool 3. The bottom hinge is provided with a spring actuated sliding bolt 21 which is designed to engagethe hole 22 when raised to alinement with it. This bolt 21 will hold thesash fixed in its lifted upright position so it can now be swung wide open into the room as shown in Fig. l, or be set at any angle desired for ventilation by the sash adjuster operated by the lift bar 6 hereto fore described. The spring actuated bolt 21 is shown in enlarged detail in Figs. 9, 10 and 11. This bolt has no special novelty but is a necessary part of theoperating mechanism of the easement window described. herein. w

In order to make the top of the sash opposite the hinged side thrust out positively, a. flat leaf spring shown in Fig. 18 is put in the window frame rabbet near the. top of the sash and opposite the top hinge. This will cause the beveled lip to clear the top jamb when the sash is lifted.

To close the window, the sash is swung shut to the position shown in Fig. 3. The.

spring bolt 21 is then drawn had; clear of the lower leaf plate 18 and the sash pushed down into the outer rabbet of the window stool by pressing downaon the bar 6 of the sash lift. The sash will now be in the position shown in Figs. 1 and 2. 7

It will be observed the hinges can be changed from a left hand to a right hand side of the sash by removing the loose pins 23 and turning the leaves 16 each up end down and again fitting hinges together with the loose pins. Therefore no right and left hand hinges will be required in the manufacture of the invention as in other casement window hinges. The sash lift and ventilatingadjuster is also made reversible. The disk 7 can be detached and the stud 10 be taken from the radial slot indicated at a and set through the radial slot 6 indicated on the opposite side.

It is to be further understood that the invention is not limited to exact details or proportions, but the right is reserved to vary the same to meet the requirements of any form or size of casement windows.

Having described my invention, I claim 1. In a casement window with. an in wardly swinging sash, a pair of hinges, each one of said hinges having one leaf slidably inserted between a short double leaf as described, the slidable leaf of the upper hinge of said pair of hinges having diagonal sliding engagement by means of diagonal slots therein with the said double leaf of said upper hinge, and the slidable leaf of the lower hinge of said pair of hinges having vertical slidin engagement by means of vertical slotstherein, with the said double leaf of said lower hinge asset forth and described and for the purposes'set forth. 2. In a-casement window with inwardly swinging sash, a. pair of hinges, each one of said hinges having one leaf slidably inserted between a short double leaf as described, the slidable leaf of the upperhinge of said pair of hinges having diagonal sliding engagement therewith, the slidable leaf of the lower hinge having a vertical sliding engagement therewith, and each of said slidable leaves being reversible for the purpose of using said pair of hinges on either the right orthe' left side of" said casement window asset forth and described.

3. In a casement window with inwardly swinging sash, a pair of hinges, each one of Said hinges having one leaf slidably insorted between a short double leaf as described, the slidable' leaf of the upper hinge of said pair of hinges'having diagonal sliding engagement therewith, the slidable leaf of the lower hinge of said pair of hinges having vertical sliding engagement there with, and said lower hinge of said pair of hinges having means for holdingthe slidable leaf of the said lower hinge fixt when ncally lifted for the" opening of said casement window sash, as set forth and described.
